1,162.390. pccificetzon Application filed November To all whom it may concern of Letters Patent.

Be it known that 1, Eco (I. OLIVER, a citizen of the limited States, residing: t Detroit, county of Wayne, State of la clngan have invented a certain new and useful A in provement in Time-Controlled Mechanism, and declare the following to be a fuli, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompan ing drawings, which form a part of this specification.

My invention relates to time controlled mechanism and the object of my improvements is to pro idea for controlling by a ciocl: mechanism the rate of travel of a mechanism impelled by an independent motor. secure ,this object in the device iilustratcd in the accompanying drawings, in which,

Figure 1, is a side elevation of a nice nism embodying my in 'ention. 2, 15 plan view of the same.

A, is a frame of the clock mechanism, nd B, is the face plate over which turns the hand a.

(J, is the hour wheel.

D, is a wheel of less diameter thanthe wheel (1 and engaging the latter.

E, is a shaft upon which is secured wheel D.

F, is a helical gear wheel upon the Sliiil H,- is a shaft resting in hearings in i frame A and extending at right an le the shaft E above the same.

G, is a helical gear wheei on the its teeth engaging the teeth wheel. F.

I, is a gear wheel upon the shaft T" is mounted IS a frame work in which a mechanism driven by an independent motor, in this case, spiral spring 1 While I contemplate that my improved device shall be used in a large variety 0 applications to which it is adapted, I hav for convenience shot '11 it in connection witl' a recording apparatus, the essential parts or which are shown mounted in the frame A.

K, is a drum mounted in the frame work A, and O, is a second drum mounted parallel to the drum K in said frame. Each of the drums have at their ends av series of teeth, and there is a band M passing over the drums K and O and engaging said teeth.

L, is the shaft upon which the drum K is .aiounted.

J, is a gear wheel upon t' shaft L. The tceti of the gear wheel J engage the teeth he go '1 cl 1.

T1, is a mounted in hearings in the frame f parallel to the drums K and O.

P, is a gear wheel upon the shaft R.

N, is a gear wheel upon the same shaft as "the drum 0, the teeth of the gear wheel P those of the gear wheei N. The spiral spring is secured at one end to the f ame I and at the other end to the shaft and is adapted to rotate said shaft to drive the drums U and L in the dir ction of the rrow, which carries the wheel J in the same urection the cioch mechanism tends to turn wheei so that the wheels J and more to ether, the one impelled by the oi he clock ot shown) and the other hy the spring By employing the helical gear wheels and F, I am ebie to ex- )rce conveyed through (i u nctiy graduate the f iy actuated mechanism. this sort there has been either the clock would i ic-"efore its proper operation prev-enter: there wouid be force added to the cioclr whi'h would result in swingin hala .ce wheel gradually to a greater travel than it was designed for and, consequently, one of the parts would he injured or broken and the clock would stop.

.The helical gears permit definite relamotion while preventing the transfer of power.

Vhat 1 claim 1 The combination of a clock mechanism, on indepcmlcntiy driven mechanism having a yielding driving means. said mechanisms being cornice-toil so as to have uniform proport onal velocities. the connecting means be retarded including a pair of helical gears, substantially as and for the purpose described.

2. The combination of a clock mechanism, .an independently driven mechanism having 5 'a yielding driving means, said mechanisms being connected seas to have uniform proportional velocities by apair of gears adapted to permit a definite relative motion While preventing the transfer-of power between said clack mechanism and independently ac- 10 tuuting mechanism, substantially as and for the purpose described.

In testimony whereof, I sign this specification in the presence of tx'vo witnesses.
